Explanation/Reference:
IRF Role Election
The process of defining the role (master or slave) of members is role election.
Role election is held when the topology changes, such as, forming an IRF virtual device, adding a new member, leaving or failure of the master, or IRF virtual device merge. The master is elected based on the rules below, in the order specified. If the first rule does not apply, a second rule is tried, and so on, until the only winner is found.
The current master, even if a new member has a higher priority. (When an IRF virtual device is being formed, all member devices consider themselves as the master, so this principle is skipped)
The device with higher priority.
The device with the longest system up-time. (The system up-time information of each member device is delivered in IRF hello packets)
The member with the lowest bridge MAC address.
